I know you added a fast forward button and all, but it would be better if it worked AFTER sending another wave of units as well. Also, I wish there were more specialized upgrades, that focused on specific units instead of the entire army (and were also therefor cheaper). Perhaps, although this is subjective, you could add more options for spells that had more utility (maybe even counter spells). Other than these 3 things (and the things other people have said), this game seems pretty solid. 4/5
